In a case in which an excess sensor which is a sensor in which the value for comparison exceeds the threshold value is present in one of the consecutive comparison processes, the detector determines that a foreign substance is present when the number of times of excess, which is the number of times at which the value for comparison exceeds the threshold value in the excess sensor reaches the first number of times. In a case in which the excess sensors of which the number is a first count that is more than one are present in one of the consecutive comparison processes, the detector determines that the foreign substance is present when the number of times of excess in each of the excess sensors of which the number is the first count reaches the second number of times, which is less than the first number of times.
